Misconceptions are misunderstandings or inequalities in solving mathematics learning problems by understanding concepts that are in accordance with mathematical rules or scientists' concepts. This journal aims to find out misconceptions about teaching arithmetic series that occur among students based on misconception indicators. The method used in this writing is qualitative-descriptive. There were 18 research subjects carried out at PGMI 3 UIN North Sumatra. There are often or still are some students who experience misconceptions about arithmetic series material, both from conceptual, strategic and systematic misconceptions, but in translation there are no more misconceptions. The data collection techniques used were observation and questionnaire questions. The results of the analysis that has been carried out are that in the process of learning arithmetic series, there are still some misconceptions among students due to a lack of understanding of the concept and not being careful in determining strategies for arithmetic series material, resulting in errors in solving problems.

This research uses a qualitative approach with a descriptive method. Research data was obtained from informants, namely principals and teachers. The data collection tools used in this study are interviews, observations, documentation studies, and carrying out triangulation, then the data is processed by data reduction, data presentation, drawing conclusions and verifying data. The results of this study show that the condition of the school's socio-cultural environment in the formation of student character at SDN 1 Kadupandak in terms of routine activities; spontaneous activities; exemplary; and conditioning has been well imolemented. However, there is an aspect that needs to be improved, namely the need for evaluation carried out by teachers related to school culture, because there are still students who need to be guided and reminded by teachers to carry out school culture activities.

The purpose of writing this article is to determine increased access and equal distribution of the potential of Islamic educational institutions. This research uses a type of library research. Library research is research carried out by reviewing various journals and related reference books. The results of his research show that one of the pillars of national education is the expansion and equal distribution of access to education. Expanding and equalizing access to education which is aimed at expanding the capacity of educational units by referring to the national priority scale which provides equal opportunities for all students from various groups of society who are diverse both socially, economically, gender, geographically and at the level of intellectual ability, and physical condition. Expanding and equalizing access provides the widest possible opportunities for the Indonesian population to be able to learn throughout their lives in order to increase the nation's competitiveness in the current era. Access to Islamic educational institutions has great significance for the development of individuals and society as a whole. This helps understand Islamic teachings, strengthens religious identity, teaches morals and ethics, understands relevant social and political issues, and helps build character and integrate religious values ??in daily life. Obstacles to access to Islamic education in this village include Lack of material books and competence of teaching staff. This factor influences the quality of education and students' understanding of Islamic teachings. Therefore, to overcome this problem, greater efforts need to be made to increase access to education, provide adequate book materials, and increase the competency of teaching staff in village areas. Teacher training plays a key role in the distribution of Islamic religious education. Effective teacher training should focus on understanding local culture, relevant curriculum, innovative teaching methods, classroom management skills, community involvement, use of technology, and development of empathy skills.
 
 

This research aims to describe the quality of the questions in terms of the validity and reliability of the four-tier diagnostic test instrument as well as identifying students' misconceptions regarding rectilinear motion material using the four-tier diagnostic test. This research is research using the Ex Post Facto method with a quantitative descriptive research type. The quality of the questions is reviewed in terms of instrument validity, namely internal validity including content, construct and language, then external validity including content and construct. The results of the analysis in this study show that the internal validity for the content, construct and language domains is 91%, 90% and 91% respectively. External validity includes content with respective false positives and false negative values ??of 9.0% and 7.33%, then the construct aspect produces a value of 0.47. The reliability of the instrument shows that rcount = 0.420. The factors that cause misconceptions experienced by students originate from within themselves, originating from humanistic thinking with a percentage of 25.98%, then from preconceptions, associative thinking, wrong intuition and wrong reasoning with percentages of 18.38%, 15.44%, 5.88% respectively, and 5.64%.

Modeling has been carried out using the STARS software to analyze the structure and chemical composition of a primary star with a mass of 2.24M_? type Algol. Algol type stars are close binary star systems that experience the Algol pradox. The Algol paradox is a situation where a star with a smaller mass turns out to have evolved further than a star with a larger mass. The results of this modeling are (1) HR diagrams (2) star structure graphs and (3) graphs of star chemical composition as a function of radius.

The purpose of this research are 1) To determine the attention of parents of class VI students at SD Negeri 122368 Pematang Siantar T.A 2023/2024, 2) To determine the mathematics learning outcomes of class VI students at SD Negeri 122368 Pematang Siantar T.A 2023/2024, 3) To determine the effect of attention parents on the mathematics learning outcomes of class VI students at SD Negeri 122368 Pematang Siantar T.A 2023/2024. This type of research is quantitative research with an ex post facto method. This research sample used total sampling, namely all class VI students, totaling 35 students, consisting of 15 male students and 20 female students. Data collection in this research was carried out using questionnaires and documentation. The data analysis technique used is a simple linear regression test and a significant test (t test). The results of the research show that there is a significant influence between parental attention (X) on mathematics learning outcomes (Y) of class VI students at SD Negeri 122368 Pematang Siantar T.A 2023/2024. This is proven by the tcount value for the parental attention variable (X) of 6.287 while the ttable value is 1.69236, so tcount > ttable (6.287 > 1.69236), with a sig value ? = 0.00 < 0.05 so it can be stated that Ho is rejected and Ha is accepted. Variable contribution.

This study seeks to ascertain the extent of student discipline in relation to their study habits and examine its impact on enhancing student academic performance. The research methodology employs a correlational design to ascertain the correlation between discipline and study habits in order to enhance the academic performance of class XII students at SMA Negeri 2 Tondano. The population consisted of 46 pupils, and the sample was obtained by a random sampling procedure or by random selection. Random sampling is a technique for selecting samples in a random manner, ensuring that every member of the population has an equal chance of being chosen. The sample size in this study comprised 30 students. The findings of the research, which employed descriptive statistical analysis, indicate that the mean student discipline score is 33.13, the student study habits score is 30.43, and the mean student learning score is 90.6. The research findings, obtained through the use of Pearson product-moment correlation, indicate that the value of rcount is greater than rtable for a sample size of 30, specifically 0.394. If rcount > rtable, it indicates that discipline has an impact on the study habits and learning outcomes of class XII students at SMA Negeri 2 Tondano. If the count of r (rcount) is greater than the count of r in the table (rtable), the null hypothesis (HO) is rejected and the alternative hypothesis (H1) is accepted, according to the proposed research hypothesis. Discipline exerts a substantial impact on the study habits and academic achievements of twelfth-grade students at SMA Negeri 2 Tondano.
